Abstract

The invention provides an oil return device at the bottom of the filter element of the oil-gas separator, which can solve the problem that the overall height of the unit needs to be increased by adopting the existing oil return device. It includes an oil-gas separator filter element and an oil-gas separator cylinder, and it also includes an oil return pipe assembly. Concentric installation holes are respectively opened on the bottom of the oil-gas separator filter element and the oil-gas separator cylinder, and the oil return pipe assembly passes through the oil-gas separator filter element in turn. The installation hole of the oil and gas separator cylinder, the oil return pipe assembly and the oil and gas separator filter element are locked by lock nuts, and the oil return pipe assembly and the oil and gas separator cylinder are connected and fixed by ferrule joints.

Description

technical field [0001] The invention relates to the field of oil injection screw vacuum pumps, in particular to an oil return device at the bottom of an oil-gas separator filter element. Background technique [0002] The filter element of the oil-gas separator has oil accumulation at the bottom during the working process, and the oil accumulation needs to be discharged from the bottom in time, otherwise the separation performance of the filter element will be affected. The oil return of the filter element of the conventional oil-injected screw vacuum pump is extended from the upper part of the oil-gas separator into the oil suction pipe to suck the oil out. This method requires a pipe joint and elbow room in the space above the separator top cover, thus increasing the overall height of the unit. , and affect appearance. Contents of the invention [0003] In view of the above problems, the present invention provides an oil return device at the bottom of the filter element ...
